Development and application of filters

development and application of filters:

before the 1980s, most engine oil filters used in China were replaceable. This kind of structure and range grading refers to a filter with opposite characteristic parameters of the experimental machine. The filter element and other parts, such as springs and sealing rings, are put into a metal shell, and the shell filter element is connected and fixed with a metal filter base that has not been contacted before through a pull rod. Its advantage is that it has low cost. It only needs regular maintenance and replacement of the filter element. The disadvantage is that there are too many sealing points. The maintenance and replacement of the filter element may leak parts, which is easy to cause loopholes, and the replacement is cumbersome

since the early 1980s, Bengbu filter general factory introduced the first spin on filter production line from Italy in China, the spin on filter has gradually been recognized and selected by domestic main engine manufacturers. The characteristic of this filter is that there is only one check valve, bypass valve and sealing point inside. The overall replacement greatly improves the sealing performance and is easy to replace. The filter element material is mostly imported filter paper, so the filtration efficiency is high, the flow resistance is small and the service life is long. At present, all domestic cars use oil filters with this structure. Most mini cars, large, medium and small passenger cars, light and medium-sized trucks, and some heavy trucks and agricultural vehicles use spin on oil filters

engine oil is an interpretation of the overall mechanical performance of the structure from the perspective of structural conceptualization. The filter is located in the engine lubrication system. Its upstream is the oil pump, and its downstream is all parts of the engine that need lubrication. Its function is to filter the harmful impurities in the engine oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving pairs with clean engine oil to lubricate, cool and clean, so as to prolong the service life of these parts. The engine oil filter is divided into replaceable type, rotary type and centrifugal type according to the structure; According to the arrangement in the system, it can be divided into full flow type and split flow type. The filter materials used in the oil filter include filter paper, felt, metal, nonwoven fabric, etc
